Answer:

The 4th term in the sequence is -18.

Step-by-step explanation:

The <em>n</em>th term of a sequence is given by the relation:

a(n)=-6-4(n-1)

Compute the 4th term in the sequence as follows:

a(4)=-6-4(4-1)

       =-6-4\cdot (4)-4\cdot(-1)\\\\=-6-16+4\\\\=-18

Thus, the 4th term in the sequence is -18.

Luis plans to purchase some new baseball bats and gloves before spring training begins. Luis wants to buy the same bats and glov
hram777 [196]

Answer:

Luis will pay for three gloves and four bats = $ 270

Step-by-step explanation:

Let the bats be represented by b and gloves by g, then according to the given conditions

3b+ g= $135----equation 1

b+ 2g= $135------equation 2

Subtracting equation 2 from eq. 1 gives

3b+ g= $135----equation 1

<u>-b -2g= -$135------equation 2</u>

<u>2b -g = 0 --------- equation3</u>

2b-g= 0

or 2b= g------ equation4

This means price of 2 bats is equal to price of 1 glove.

Putting value of g in eq. 1 from eq. 4

3b+ 2b= $ 135

5b= $135

b= 135/5= 27

Price of 1 bat = $ 27 and price of 1 glove= 2*27= $54

Luis will pay for three gloves and four bats

= 54*3 + 4*27

= 162+ 108

= $ 270
